What is the significance of using classes in ABAP's object-oriented programming?

Using classes in ABAP's object-oriented programming is significant primarily because it promotes code reusability and structure. By defining classes, developers can encapsulate data and the functionality that operates on that data in a single coherent unit. This encapsulation not only makes it easier to manage and organize code but also allows developers to reuse classes across different programs and applications, thereby reducing redundancy.

The structured approach provided by classes enables clear definitions of responsibilities in the code. Inheritance and polymorphism—key features of object-oriented programming—further enhance code reusability by allowing developers to create new classes based on existing ones, thereby extending functionality without the need to rewrite code. This modular approach makes maintenance and updates more straightforward, as changes need to be made in one location rather than throughout numerous individual scripts.

The other choices highlight different aspects of programming, but they do not capture the essence of why classes are used in ABAP specifically. For instance, while it could be argued that less code is a benefit of object-oriented design, the primary advantage lies within the principles of reusability and structured programming. Similarly, classes do not directly relate to how data is stored or manipulate database transactions; these functions are more about how the objects interact with underlying mechanisms rather than
